Engine Test and Development

We have experienced personnel for engine assembly and test, as well as computer controlled, correctly calibrated dynamometer test facilities, in house. We have on-site facilities for CAD design, machining, balancing, honing, clean assembly, and much more. Recent work has included projects as varied as the detail development and initial test of a new proposal in engine remanufacture, to the extensive analysis of a production tolerance/quality issue causing an NVH problem.

 

In addition to CNC machining, we have in-house facilities for balancing rotating components, boring and honing machines, hand-grinding (die-grinding) equipment for detail shaping and smoothing of ports or other features. Then also full assembly and test facilities to complete the working engine.

Dynamometer Facilities - Engine Testing and Mapping

JE Motorworks are delighted to offer an up-dated engine dynamometer testing service to petrol engine customers from Autumn 2021. We aim to provide short lead times and efficient, practical solutions. Short sign-off tests and long-term durability tests can be accommodated.

 

This is particularly aimed at classic car owners and kit car enthusiasts, as well as customers who like to build their own engines and who then wish to test or calibrate them before installing them into vehicles. Our comprehensive fuel delivery system allows us to run fuel injected or carburettor-based engines on either of our two test cells, details of which are below.

 

Cell One is equipped with a Schenck D700 Water Brake dynamometer that has a maximum speed of 7500rpm and a massive 3000Nm / 700Kw (940hp) capability that lends itself well to boosted applications or very large capacity engines. The characteristics of a water brake are particularly suited to engine running-in and power curve runs, and also durability work.

 

 

 

 

Cell Two is a perfect dyno for engine calibration work or for engines with a lower specific power output through the installation of a Schenck W230 Eddy Current dynamometer, working to a maximum of 7500 rpm and 730Nm / 230Kw (308hp). The high-resolution control lends itself especially to steady state mapping or jetting work, perfect when optimising specific points in the rev range and more controllable than using a rolling road. Equally, it is perfectly suitable to run-in and power check a smaller engine.

 

Calibration work at this level can be managed by the customer but we can assist, and we have contact with SCS Delta, Motec, and others should you have a need for specialist support.

 

We offer a range of services including an initial consultation and advice, the opportunity to specify what testing and what data you require, as well as agreeing any works that arise from a particularly unique engine (including design of mounts etc), and finally writing reports on your engine post-test with graphical data if required.

 

Prices start at £95/hour for installation and removal and £120/hour plus fuel cost for actual running hours. We can also quote for specific design work and associated manufacturing to suit your unit.

 

Please call Dave Warner to discuss your requirements in the first instance.
